Description

The PTHF4900DK can be used for a variety of applications

from chemical metering, to temperature regulating, to energy

management. The infinite adjustability from 1 to 99 provides

accurate percentage on control over a wide factory fixed cycle

period. When mounted on a metal surface, it can be used to

drive solenoids, contactors, relays, or lamps, up to 20A steady,

200A inrush. The PTHF4900DK is the suggested replacement

for the PT Series.

Operation (Percentage)

Upon application of input voltage, the output energizes and

the T1 ON time begins. At the end of the ON time, the output

de-energizes and the T2 OFF time begins. At the end of the

OFF time, the output energizes and the cycle repeats as long as

input voltage is applied. Increasing the ON time decreases the

OFF time. The total cycle period is equal to the ON time plus the

OFF time. The total cycle period is factory fixed. ON time range

is 1 to 99 percent of cycle period.

Reset: Removing input voltage resets the output and time

delays, and returns the sequence to the T1 ON time.
